Building Your Brain Vault
(Personal Knowledge Management System)

In today's fast-paced world, the ability to retain and synthesize information from various sources is crucial for personal and professional growth. A Personal Knowledge Management (PKM) system serves as a second digital brain, helping you organize, retain, and utilize knowledge from diverse resources such as seminars, sessions with mentors and experts, books, courses, universities, and other sources of knowledge. This blog post will guide you through building your own PKM system, which we will refer to as the "Brain Vault."

Why Build a Personal Knowledge Management System?

A PKM system is essential for several reasons:

  1. Organization: It helps you systematically organize your knowledge and resources.

  2. Retention: It aids in retaining information over the long term.

  3. Synthesis: It allows you to synthesize information from various sources.

  4. Utilization: It enables you to use your knowledge effectively for work projects, personal development, and other purposes.

Tools for Building Your Brain Vault

Two highly recommended tools for building your PKM system are Notion and Obsidian.

Notion

Notion is an all-in-one workspace that combines notes, tasks, databases, and calendars. It is highly customizable and can be tailored to fit your specific needs.

Key Features:

  • Databases: Create databases to organize books, courses, seminars, and other resources.

  • Templates: Use templates to standardize the way you capture and organize information.

  • Linked Pages: Link related pages to create a web of interconnected knowledge.

  • Tags: Use tags to categorize and filter information.

Obsidian

Obsidian is a powerful knowledge base that works on top of a local folder of plain text Markdown files. It is designed to help you build a network of linked notes.

Key Features:

  • Graph View: Visualize the connections between your notes in a graph view.

  • Backlinks: Easily see which notes link to the current note.

  • Markdown: Use Markdown for easy formatting and compatibility with other tools.

  • Plugins: Extend functionality with a wide range of community plugins.

  • Link Notes: Use Obsidian to link related notes and create a network of knowledge.

  • Tag Information: Use tags to categorize and filter information based on topics, projects, or other criteria.

Step 3: Synthesize Information

Synthesize the information to create new knowledge:

  • Write Summaries: Write one-pagers summarizing key topics and insights.
